My bet is that Marbles is somewhat related to a Japanese pachinko machine, or to a Galton quincunx. Both of those predictions are sufficiently vague to guarantee the appearance of at least partial prescience.

Guessed the name and function of an upcoming module

Then, in this thread about an updated Waldorf string synth, Olivier said:

Probably a 168 or 180 MHz F4 or F7 compared to the 72 MHz F3 they used on the original product.

BTW I figured out how they did it Full polyphony and several saw+square “harmonics” per note, just for slightly more than the cost of 12 Polyblep oscillators. The code will be made available in a few months.

And so, putting these tidbits of information together, my guess is that one of the new MI modules will be called Looms and it will be a polyphonic voice module, using the efficient method for generating multiple band-limited waveforms to which Olivier refers. The name Looms makes sense, sticking to an Industrial Revolution theme, since we’ve had Braids and Warps, and Wefts doesn’t quite seem right.

My other wild guess, backed only by an inkling, is that another of the new modules will be Cascades, and it will be a complex envelope generator (or more likely, generators).

Facebook is the only place where that content, which another user requested, could be found…and which was posted by Olivier himself on the Mutable Instruments Facebook page.

So…tough luck!

Back on topic, that Facebook thread was updated as recently as 16 weeks ago, so it still seems to have some life to it. There was also a screenshot from Olivier that showed a purchase order for something called “module MARBLES v7.0”.

Olivier’s post stated on October 4, 2017:

“It’s in the pipeline! 6-7 weeks to get the first 20 units (pre-production run), then a couple weeks of hardcore testing, then 2-3 months for mass production…”
